ok you see what happens when you lay the epoxy on thick? that’s what happens (top image). the good news is: it all sands out. I HIGHLY recommend an orbital sander with a shop vac suction attachment. makes your shop way cleaner but doesn’t eliminate all the dust. that’s gonna be there and if it bothers you, open a door. get some ventilation. because you’re just starting this epic journey into the Sahara of cedarstrip canoes, friend. strap in. the bottom image is the ‘after’ sanding. See? it all goes away.
